I feel this article is not very balanced. It does not mention that having a colonoscopy is not without risks (perforation is 1 in 2000) and could potentially lead to death (3 in 100,000) [0]. Combining this with the high false positive rate of stool-based tests puts you in a complex situation when you do get a positive outcome of these.
